In polluted environments, dolphins gradually accumulated toxins in their body fat, and the larger the dolphin, the more accumulated toxin it can tolerate. Nearly 80 percent of the toxins a female dolphin has accumulated pass into the fat-rich milk her nursing calf ingests. Therefore, the unusually high mortality rate among dolphin calves in the industrially contaminated waters along Florida’s Gulf Coast is probably the result of their being poisoned by their mother’s milk.
Which of the following, if true, most strengthens the argument?
分析A选项
分析B选项
分析C选项
分析D选项

原文结论是，Dolphin高的死亡率是因为poisoned by their mother's milk。
求加强。
A 还没断奶妈妈就被杀的first born calves 的存活率高，也就是说很早就断奶，这样喝妈妈奶水少，当然中毒就浅或没有中毒，所以加强原文，高死亡率是因为奶水。
答案A

a 读了半天……还是觉着怪怪的第一次看的时候觉得是w，但是看了一遍发现只有a提到的东西对……a不是说firstborn dolphin calves的存活率比那些还没断奶mother就被杀了的海豚高吗？…

哦懂了……是firstborn 的存活率在还没断奶mother 就被杀了的海豚之中时最高的。……那这个firstborn是啥意思……第一次出生？早出生的？早出生的喝的不是应该比晚出生的多吗？存活率不应该是最低的吗……

D为啥不对呢？海豚成年以后集聚毒素的速度比幼崽时期慢，说明幼崽喝的母奶里面的毒素在幼崽身体里面集聚得快
